Resumo

The superoxide dismutase mimetic EUK-8 has been reported to extend lifespan in the nematode Caenorhabditis elegans. However, in five trials administering EUK-8 in liquid culture with E. coli, and two trials using defined liquid medium, we observed no increase in C. elegans lifespan. Instead we saw a dose-dependent reduction of lifespan and fertility. We conclude that extension of C. elegans lifespan by EUK-8 may only occur under very particular culture conditions.
